Natural selection is an evolutionary process in which individuals with survival-promoting traits reproduce at higher rates. These favorable traits become …
Natural selection influences the frequencies of particular alleles and phenotypes within populations in several different ways. Primarily, natural …
When the fitness of a trait is influenced by how common it is (i.e., its frequency) relative to different traits within a population, this is referred to …
Organisms that are well-adapted to their environment are more likely to survive and reproduce. However, natural selection does not lead to perfectly …
Directed evolution is defined as a method to harness natural selection in order to engineer proteins to acquire particular properties that are not …
Lignocellulosic biomass is an abundant, renewable feedstock useful for production of fuel-grade ethanol and other bio-products. Pretreatment and enzyme …
Multicopy plasmids are extremely abundant in prokaryotes but their role in bacterial evolution remains poorly understood. We recently showed that the …
